Answer:

A) The net force

Explanation:

If two forces of equal strength act on an object in opposite directions, the forces will cancel, resulting in a net force of zero and no movement.

Anettt [7]

Answer:

The average current is 19.567 A

Solution:

As per the question:

Charge, Q = 8.0\times 10^{- 4}\ C

Time, t = 35\times 10^{- 6}\ s

Now,

We know that current is constituted by the rate of transfer of the charge per unit time. Thus we can write:

I = \frac{Q}{t}                 (1)

Now, the charge that was transferred is 86 % of the original value.

Therefore,

We replace Q by 0.86Q in eqn (1):

I = \frac{0.86\times 8.0\times 10^{- 4}}{35\times 10^{- 6}} = 19.657\ A

A car travels in a straight line with an average velocity of 80 km/h for 2.5 h and then with an average velocity of 40 km/h for
maks197457 [2]

Answer:

260 km

65 km/hr

Explanation:

The displacement of an object is the distance moved by that object in a particular direction.

velocity = displacement / time, therefore,

Displacement = velocity * time.

Total displacement for the 4 HR trip = displacement for 2.5 hr + displacement for 1.5 hr

total displacement = (80 * 2.5) + (40 * 1.5)

Total displacement = 200 + 60

Total displacement = 260 Km

average velocity for the total trip = total displacement / total time taken

average velocity = 260 km/ 4 hr

average velocity = 65 km/hr
